Dede said almost 7 years ago on Decoding and Interacting with Barcodes :

the best tutorial ever my dear friend! do you have this same project in GitHub? thanks for share your knowledge!

In my case i copyed and paste all code in my project, and don't appear nothing in my view using this <div id='barcode-scanner'></div> there.

Do you know if have something else to do? because "i think" that have to appear my webcam in the view, right? or i need to do more things?

Thanks!
